CLUTCH FOR RODS.

SPECIFICATION forming part of Letters Patent No. 410,275, dated September 3, 1889.

Application filed May 27, 1889. Serial No. 312,254:- (No model.) 4

To all whom it may concern:

Be it known that I, REUBEN IIADFIELD,'L citizen of the United States, residing at Akron, Summit county, Ohio, have invented anew and useful Improvement in Clutches for Drawing Metal Rods, of which the following is a specification.

The main object of my invention is to firmly and conveniently hold and release cold-metal rods in drawing them through dies.

In the drawings forminga part of this specification, Figure 1 is a side elevation of the clutch. Fig. 2 is a plan of the same. Fig. 3 is a vertical longitudinal section of the same, and Figs. 4 and 5 are respectively a side and top View of the lower rod-holder.

Several clutches, as shown in the drawings, may be used in the same holder a, and so arranged that several rods 19 may be drawn at the same time.

The clutch consists of a frame f, a bar 0, formed with an edge 0 to enter the rod (Z to be drawn, and with a hinged arm or lever 6, formed with an edge e to enter the rod opposite edge a. Holder f is formed at f to arrest the downward movement of lever e when it has sufliciently entered rod (1 to retain the rod while it is being drawn. Holder f may be attached to the draw-block of a machine by means of a pin through hole g in part It is formed with a longitudinal hole or entrance 0, into which rod cl may be introduced when lever e is lifted in order to raise edge e and permit the rod to enter under it. Holder f is formed to receive bar 0, which is held firmly in position by a wedge h, and may be adjusted for different-sized rods by means of lining t'.

On lifting lever a sufficiently rod 01 may be introduced into hole 0 in holder f, and then, by turning down the lever until its edge e is in contact with rod d and drawing the-latter the edges o e are forced into the rod until the arm of lever e is arrested at f on holder f. \Vhen the rod has been drawnthrough a die, it may be released from holder f by raising lever e.

I claim as my invention- '1. In a clutch for drawing metal rods, a

holder ,or frame, in combination with a hinged lever and a bar, each formed with an edge to enter the rod on opposite sides of the latter, substantially as described.

2. In a clutch for drawing metal rode, a holder or frame, in combination with a hinged lever and an adjustable bar, each formed with an edge to enter the rod, the lever being adapted on lifting the same to allow the rod to enter the holder, and the latter formed and adapted to arrest the lever when the edge of the latter has sufficiently entered the rod, substantially as described.
